To all whom it may concern:

Be it known that we, RoLLIN H. WHITE and CLARENCE G. WHITE, citizens ofthe United States, and residents, respectively,

of Cleveland Heights village, in the county.

of Cuyahoga and State of Ohio, and Haiku, Maui, Territory of Hawaii,have invented a certain new'and useful Improvement in AgriculturalMachines, of which the follow-Q ing is a full, clear, and exactdescription.

This invention relates to self propelled agricultural machinery, theobject belng to provide as a unitary structure a chassis carrying apower plant and also carrying implements which work upon the, soil.

In the present instance, the agricultural machineshown is a selfpropelled disk harrow plow, although the particular construction shownis' only byway of disclosure, and it is notjintended to limit theinvention to the precise form of machineshowny'ex cept wherein theclaims shall so specify."

.Generally speaking, the invention comprises the. elements andcombinations thereof set forth in the accompanyingcl'aims;

Reference should be had tol the accompanying drawing forming a part ofthis specification, in which- Figure 1 is a side elevation 'of an fagriat 6, audit comprises an engine preferably of the explosive type whichis'provided with the necessary appurtenances for its, operation. Therotation of the crank shaft is transmitted through-an intermediateshaft,

indicated at 7, to gearing within with'the casing 8, this gearing beingof the change speed type, so as to permit the operation at differentspeeds of the instrumentalities with which it is connected.

A seat 9 for'the driver of the machine is provided directly behind thepower plant he power plant s generally represented and ad acent are thenecessary levers for the regulation ofthe engine, as well as for theoperation of'the change speedgearing f and the brakes: There is also-asteering wheel indicated at 10-which at its lower end isprovided with aflanged Wheel 11'. adapted tocooperate -with a" cable to the steeringapparatus, as will later bedescribed. 1

gedlangular strlps, such as represented atllSz} -1- d Upon the outerendflof eachroller section the shaftsat their outerends'being' mountedin rear. extensionsjof the sideinembers 11 and 12 of the sub-frame andat'their; inner ends extend into a gear casing 24 'in which is adifferential gear mechanism, so-that the shafts 22 and 23 may rotate atdifferent relative speeds. Power is imparted'to the gearing within thecasing- 24xby means of achain gear drive, as represented at 25 in Fig.1.-

The side member 1 ofthe'chassis is extended toward the rear, and theside member 12 of the sub-frame extends towardthe rear ina paralleldirection, the portion 12 'of this side member being bent upwardly, asindicated in-Fig. 1, and at the rear portion is again bent to extendhorizontally, as represented .at 12. This portion 12 is joined totheside 1 of the chassis by cross members 2 6and 27. V

Joining the members 26 and 27 is a cross brace 28. This cross. brace,together with the portion 12 and the sides 26 and 27 supporta bracketprovided with arms, one of Y which'is indicated at 29. These arms onmeeting provide" a central hub, through which extends a shaft 30. Thisshaft at its lower'end is joined to the axle upon which the wheels 31are mounted. The wheels 31, as will be seen from Fig. 2, have a broadflat periphery except for a central projection or ridge which cuts intothe ground, and thereby prevents sideslipping of the wheels 31 withrespect to the ground.

To the upper end of the shaft 30 is secured a wheel 32, provided with agrooved periphery which is adapted to engage with a cable 33, whichcable engages with the grooved pulley 11 at the lower end of thesteering wheel. It will therefore be seen that operation of the steeringwheel will produce corresponding rotation of the pulley 32, so that thewheels will be turned in the direction desired to accomplish thesteering of, the machine.

The side 11 of the sub-frame is extended toward the rear and is bent atan angle to provide a portion 11 thereof, as indicated in Fig. 2.Mounted upon this frame portion 11 are frame members 31, 35 and 36.These members extend diagonallywith respect to the axis of the chassis,and provide framework for implements which are to work upon the groundand we therefore term this frame the implement carrying frame. Themembers 34: and are at their rear ends joined to a cross piece 37 whichis suitably joined by a brace to the side l, of the chassis which liesdirectly above it The member 36 is joined at its rear end t6 the member35 by means of a brace 38, which extends between these last mentionedmembers. The 'members' 35 and 36 are joined by a cross piece 39 at itsfront end, and the members 3- and 35 are joined by a cross piece a0 atthe front end, as will be seen from an inspection of Fig. 2. Near theopposite ends of .the members 34 and 35, to that just mentioned, is abrace 41 which serves as a joining means between these members.

The braces 38 and 41 are shown in Fig. 3, and comprise, as will be seenfrom this figure, upwardly extending portions which form journals. Adescription of the brace 41 and its cooperating parts will be given, itbeing understood that the construction of the brace 38 with itscompanion parts is the same. The journal formed at the upper end of thisbrace L1 accommodates an elongated hub 42. of a gear 43. Through thesleeve 42 there extends a shaft 44; which is provided with a spline 45,by which it is secured to the hub 42, this construction permittingrelative vertical movement between the shaft and sleeve, but insuringtheir rotation together. At the lower portion of the brace 41 a journalis provided, as indicated at 45. Through this journaled portion extendsa sleeve 46,thc shaft 44 passing through this sleeve, as will be seenfrom the drawing. Near its lower portion the sleeve 46, is bifurcated toform arms 47 which unite at the lower portion and provide a journalsupport for a tubular shaft 48. This tubular shaft in reality consistsof a number of parts which are adapted to engage with disks, one ofwhich is represented at 49,- the disk being secured between faces ofadjacent sections of the hollow shaft. These sections of the hollowshaft are mounted upon a solid shaft 50 to which they are rigidlysecured. The bifurcated portion of the sleeve 46 forms a suitablemounting for a gear 51 which is rigidly connected with the shaft 44. Thegear 51 is provided with teeth which mesh with teeth carried by the disk49 which is the disk adjacent to the sleeve 46. Rotation of this disk 49causes rotation of the tubular shaft 18, and by so much causes'rotationof the gang of disks which are carried upon the shaft.

The sleeve 46 is provided with teeth 46 upon its face which engage withteeth upon a pinion 52, this pinion being carried upon a shaft 53 whichextends longitudinally of the implements carrying frame, as will be seenby reference to Fig. 2. Upon this shaft 53 is a worm wheel 54 which. isengaged by a worm 55 carried upon a transverse shaft- 56. This shaft isjournaled in bearings carried by the frame members 34, 35 and 36. At oneend this shaft is provided with a handle 57 by which the shaft may beoperated, and through the train of mechanism described will cause theelevation and depression of the sleeve i6, this being accomplishedwithout in any way interfering with the rotation of the shaft .44.

The mounting of the-operative mechanism for the gang of disksrepresented at 58 in Figs. 2 and 3 is exactly the same, and furtherdescription will not be necessary, it being understood, however. thatthe gang of disks 58 is operated, so far as the raising and loweringthereof is concerned, entirely distinct and "independently from the gangof disks which have just been described.

The gear 43 and the companion gear 59 which causes the turning of theshaft that rotates the gang of disks 58 are both in mesh with a gear 60which is mounted upon the end of the shaft 61. This shaft extends withina gear casing ()2 which at its upper end forms a journal for the shaft(31, and a seat for the gearftiO. At its lower end, the

gear casing provides a journal for the shaft 61 and at this portionthere is mounted upon the shaft a gear 63-which cooperates with thedriving mechanism of the power plant in a manner which will be.presently described. This gear casing is supported upon cross members(it which are secured to the frame members 35 and 36.

The implement carrying frame has depending therefrom a platform 65, uponto operate the cranks by which the gangs of disks are raised andlowered.

Extending rearwardly from the gear case is a power shaft 66 which isprovided with a flexible joint 67 at the forward end thereof, and aflexible joint 68 near the rear. This shaft extends within the gearcasing 62 and is provided with a gear which meshes with the gear 63,thereby providing a flexible connection for transmission of power fromthe power plant to the gear 63, which through the train of mechanismpreviously described, causes the rotation of the two gangs of diskswhich are carried by the implement carrying frame.

IVhile we have shown and described two gangs of disks, we do not wish tolimit ourselves in this particular, inasmuch as one gang of disks may beused where this is desirable. In the present instance, we have shown thetwo gangs of disks of different diameters, the leading gang of disksbeingof less diameter than the following gang, it being intended thatthe leading gang shall cut into the soil, first taking a light out,followed by the rear gang of disks, which will take a deeper cut, andalso widen the furrow. \Ve do not wish to confine ourselves to thespecific form of implements used for operating upon the ground, inasmuchas other forms of implements than disks may be used in this connection,without departing from the spirit of this invention.
